Rolling down the roller coasters

Summer Fun

Over the summer my mom, aunt, cousin, and me decided to go to Six Flags Great America. We went to Six Flags because every summer we go somewhere and this summer we decided to go to Six Flags. To get to our hotel we drove 3 hours from Green Bay and then from our hotel to Six Flags we only drove 5 minutes down the rode. We only went from August 21st to August 22nd. On August 21st we rode almost every single roller coaster there. The next day we went back and got on all the roller coasters we didn't the other day and then went to the waterpark they have there. The waterpark wasn't that big so we only spent around 2 hours there and then went back to the amusement part of the park. We ended up riding a couple roller coasters twice and then decided to head home.

The science of it

CONNECTION 1 - G-Forces

When you go up a roller coaster could you feel the gears working and the gears pulling you up? Well the gears play part in pulling you up but so do G-forces. G-forces change constantly, they can go from 0-10 within a matter of seconds. As you accelerate you can physically feel the G-forces going up rapidly but once you start going down they go down just as fast. This relates to science because of physics. The physics of it is that G-forces can go from 0-10 within seconds and that you can physically feel them. G-forces are also in every ride and every ride has something to do with physics.

CONNECTION 2 - GRAVITY

Gravity plays a part in almost everything but what you probably didn't know was that it definitely plays a part in roller coasters. Most people think it's all gears and control but really gravity is a big part in roller coasters. As you go down on a roller coaster the only thing the gears do is push you over the edge then gravity pulls you down to the bottom. If gravity didn't exist then the cart would just be sitting on the edge waiting to go down but without gravity it wouldn't be able to go down. This relates to science because many scientist study gravity and if the scientist never found out that gravity keeps you down there wouldn't be things like big drops on roller coasters.

I wonder...

1. How do they measure g-forces?

2. Does the amount of g-forces have anything to do with how the cart/track was built?

3. When going down on a ride like the giant drop is it all gravity doing the work or is there another factor?

4. Do the owners of Six flags great America know all the different g-forces in the roller coasters?
